What is Nyuto Hot Spring Area?
Nyuto Hot Spring Area (乳頭温泉郷) is a collective name for hot springs scattered around the foothills of Nyuto Mountain within Towada-Hachimantai National Park in Semboku City, Akita Prefecture. Seven hot spring inns exist deep within a pristine beech forest at elevations of 600-800 meters, each possessing its own source spring, making it known as one of Japan’s premier secret hot spring regions.
Receiving approximately 150,000 overnight guests annually, this hot spring area boasts over 350 years of history dating back to the Edo period, and still retains strong traditional hot spring bathing culture. With more than ten different spring sources throughout the area, the greatest charm lies in the ability to enjoy diverse spring qualities.
Located to the northeast of Lake Tazawa and surrounded by primeval beech forests that change with the seasons, the environment provides a healing space away from urban hustle and bustle. Despite being accessible by bus from Tazawa Lake Station on the Akita Shinkansen, it offers the rare opportunity to fully experience the atmosphere of a hidden hot spring nestled deep in the mountains.
History and Origins of Nyuto Hot Spring Area
The name Nyuto Hot Spring Area derives from Nyuto Mountain that rises in this region. Nyuto Mountain stands at 1,478 meters in elevation, named for its mountain shape resembling a breast.
The spring’s history is ancient, with Tsuruno Yu Hot Spring, the oldest, said to have opened in 1638 (Kanei 15). It was used as a bathing place by the Akita domain lord Satake clan and flourished as a base for matagi (people who made their living through hunting). Already in the Edo period, hot spring bath guests visited, and it was known as a therapeutic destination at that time.
Since the Meiji period, it has continued to be loved by local people and hot spring bath guests, and from the 1950s onward gained nationwide attention alongside the hidden hot spring boom. Even today, some inns lack sufficient electricity and running water, retaining the rustic atmosphere of traditional hot spring bathing establishments.
